Be it known that I, JOHN J. BAUSOH, of

Rochester, in the county of Monroe and State of New York, have inventeda new and use ul Improvement in Eyeglasses, of which the following is aspecification A Figure 1 represents one of my improved eyeglasses. Fig.2 is a detail view of a portion of the same. Fig. 3 is a detail sectiontaken through the line .1; .r, Fig. 1. Fig. 4 is a detail section takenthrough the line 3 3 Fig. 3. Fig. 5 represents a modification of thesame. Fig. 6 is a detail section ofthe same take through the line 2 z,Flg. 5.

Similar letters of'ret'erence indicate corresponding parts. i

The invention will first be described in connection with drawing, andthen pointed out in the claim.

A represents the frames or glass parts, which are connected by theconnecting or how spring B, secured to projections formed upon the upperparts of said frames A. U are the nosepieces, the upper parts or halvesof which are secured to light springs D. The springs D extend along thesides of the nose-pieces 0, next the glass frames A, and their lowerends project a little below the lower ends of the said nose-pieces G,and are secured to projections formed upon the lower parts of the saidframes A. The upper ends of the springs D project above the upper endsof the nose pieces 0, are bent over, and have heads formed. upon themwhich pass through slots in the guards E. The guards E may be inwardextensions of the ends of the connecting or how spring B, as shown inFig. 5, or they may be separate pieces, as shown in Fig. 1.

If desired, the slot may be formed in the bent-over upper ends of thesprings D, and the heads may be formed upon the ends of the guards E, asshown in Fig. 5.

By this construction, when the eyeglasses are in use, the nose-pieces Oand springs D take about the position shown in Fig. 2,

biingiug mm) play the elasticity of the lower part of the said springsI), and the elasticity of the lower part of the nosepieces U, whichenables the nose-pieces to adjust themselves to the nose of the wearermoreaccurately, and with a more delicate pressure, than when they areconstructed in the ordinary way. By this construction, also,'the upperends of the nose-pleces are kept in place, and the lower parts, when theeyeglass is not in use, are held firmly down on the nose-piece. springsby the elasticity of the latter, thus preventing the nose-pieces frombeing caught and breaking, to which they are liable when either end ofthe nose pieces is open. One of the frames A is provided with a handle,F, and catch-pin G, and the other frame is provided with a catch, H, tocon tine the frames when folded together.

Having thus described my invention, Ielaim as new and desire to secureby Letters PM? ent- An eyeglass provided with self= adjustingnose-pieces closed at both ends, as and for the purpose described.
